E-Commerce Safeguards Businesses must have some form of security certification to give customers a level of comfort Look for visual indicators a website is secure: URL changes from “http://” to “https://” – with the “s” standing for secure socket layer Shop at well-known, reputable sites Because online shopping eliminates a salesclerk or other human intermediary from the transaction, it can actually be safer than traditional retail shopping. In addition to using some basic common computing sense such as having a firewall and up-to-date antivirus software on your computer and using strong passwords for all your online accounts, there are several important guidelines to follow to ensure your online shopping experience is a safe one: Look for visual indicators that the website is secure. Check that the beginning of the URL changes from “http://” to “https://”—with the “s” standing for secure socket layer. Also, look for a small icon of a closed padlock in the toolbar (in both Internet Explorer and Firefox) and a green-colored address bar, indications that the site may be secure. Shop at well-known, reputable sites. If you aren’t familiar with a site, investigate it with the Better Business Bureau or at Bizrate.com. Pay by credit card, not debit card. Federal laws protect credit card users, but debit card users don’t have the same level of protection. When you place an order, check the return policy, save a copy of the order, and make sure you receive a confirmation number. Make sure you read and understand the fine print on warranties, return policies, and the retailer’s privacy statements. If the site disappears overnight, this information may help you in filing a dispute or reporting a problem to a site such as the Better Business Bureau. Avoid making online transactions when using public computers.
